The Foo Fighters postponed several shows at the last minute over the weekend, citing a “family emergency” for pushing dates in Lexington, Memphis and Nashville.

The Lexington show, scheduled originally for Saturday at Rupp Arena, was called off just hours before showtime, according to Kentucky.com. Rupp Arena sent out a press release announcing the show’s postponement at 3:22 p.m. – just over four hours before the schedule 7:30 p.m. start time. The concert will be rescheduled for May 1, 2018 at a time yet to be announced.

“The band sincerely apologizes for any inconvenience and looks forward to returning to rock Lexington in May,” the release said.

In a message posted to the band’s twitter account on Sunday afternoon, shows on Monday at Bridgestone Arena in Memphis and Tuesday at Nashville’s Fed Ex Forum were also moved:

The Memphis concert has been moved to Tuesday, May 3, 2018. The Nashville concert will be rescheduled, but a date has yet to be announced.

“All tickets previously purchased will be honored for the new dates,” the band’s statement says. “If you are unable to attend, refunds are available at the point of purchase.

“Foo Fighters apologize for any inconvenience caused and look forward to seeing fans at the new dates.”

Specifics regarding the emergency that necessitated the cancellations have yet to emerge.
